To all whom it may concern:

Be it known that I, OTTO M. BERGMAN, a subject of the King of Sweden, residing at Rochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Hydroaeroplanes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a hydro-aeroplane.

The object of the present invention is to provide a simple, practical and efficient hydro-aeroplane of strong, durable and comparatively inexpensive construction designed for running or skimming over the top of the water and also forfiights in the air and capable of starting and landing both on the ground and on the water.

A further object of the invention is to provide a hydro-aeroplane of this character adapted for use at seaside resorts as a pleasure car and also for use as a passenger carrying ocean going car and capable of enablingthe means for propelling it on the surface of the water to be utilized in starting the machine for flying purposes, especially when the machine is made for carrying a relatively large number of passengers or a large amount of merchandise.

With these and other objects in view, the

- invention ,consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: 7

Figure 1 is a front elevation ofa hydroaei'oplane constructed in accordance with this invention. Fig. 2 is a side elevation of the same. Fig. 3 is a lan View. 4 ,Figs. 4 an 5 are detail views illustrating thev construction of the ball bearings.

Like numerals of reference 'designatecorresponding parts in all the figures of the drawings. v

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the machine comprises in its construction a frame 1 constructed of tubes or pipes and connecting couplings 2 and the said frame, which may be made of any desired size and constructed of any suitable metal, is preferably braced at opposite sides by crossed braces 3vand reinforced by side trusses 4 located at the upper portions of the sides of the frame as clearly shown in Fig. 2 of the drawings.

The machine is equipped with hollow cylinders or wheels 5 and 6 located at the front, center and rear portions of the frame and disposed in pairs, the members of the several pairs being arranged in spaced relation to provide a central longitudinal space 7 centrally of the frame for the accommodation of the passengers, and the motors and other mechanism with which the machine may be equipped. The front and intermediate wheels are of the same construction and the rear wheels or cylinders 6 are preferably provided with paddles or blades 8 for enabling the rear wheels to operate as driving wheels and to effectively propel the machine on the surface of the water. The wheels or cylinders, which may be made of any desired size, can be constructed'of any suitable material, thin metal being preferably employed, and air may be exhausted from the same to form vacuums for reducing the weight, or they may be filled with a gas lighter than air. Thewheels or -cylinders are provided at their sides or ends with suitable trunnions or journals 9 and are preferably mounted in ball bearings 10 of any desired construction.

The rear driving wheels orcylinders are equipped with pulleys 11 and are connected by belts 12 with pulleys 13 mounted on the shaft 14; of an electric motor 15 adapted to be operated for driving the-machine over the surface of'the water and also for starting the machine to assist front propellers 16 and 17 when the machine is preparing to make a flight in the air. The propeller 16 is centrally arranged at the front of the maclflne and is mounted on the shaft 18 of a mbtor 19 which may be an internal combustionengine or any other type of motor or engine. The propellers 17 are mounted on shafts 20 and are located above and at, I o posite sides of the central propeller; 16, the drawings,

s c learly shown in Fig. 1 of and'the said shafts 20 are connected with the motorshaft by belts 21 and. 22, the belt 22 being crossed so that theside propellers are driven in opposite directions. The belts21 and 22 are arranged on suitable pulleys 23 and 24, but any other form of gearing may be employed for transmitting motion from the motor to the propellers and to the rear driving wheels. I

The machine is equipped with front and rear supporting planes 25 and 26 and it has a rudder 27 which may be operated by any suitable. means and if desired adjustable side planes may of course be employed. The supporting planes 25 and 26 are arranged above the front and rear portionsof the frame and are supported by rods 27 and suitable braces 28 and 29. Any suitable bracing means may of course be employed and the size of the planes will be proportioned to the load to be carried.

The machine is adapted for pleasure purposes at seaside resorts and also for use as a passenger carrying machine and may be advantageously employed in sighting submarines as it will skim rapidly over the surface of the water and also fly through the air and, owing to the separate motors, the machine may be rapidly and .easily controlled and a high rate of speed may be attained with a maximum safety. The hollow cylinders or wheels, which are both air tight and water tight, constitute buoyant rotary elements and, While the driving mechanism is shown connected with the rear wheels or cylinders, the paddles and the mo- 'tor may be applied to any of the wheels or propellers located at the front of the frame, a motor having a shaft carrying the central propeller, and'means for connecting the side propellers with the motor.

In testimony whereof I aflix my signature in presence oftwo witnesses.
